MAGAZlNE-SHOTGUN.

SPECIFICATION forming part of Letters Patent No. 469,900, dated March 1,1892.

Application filed April 6, 1891. Serial No. 387,877. (No model.)

To all whom it may concern.-

Be it known that I, WILLIs H. OSTRANDER, a citizen of the United States,residing at Merced, Merced county, State of California, have inventedanImprovement in Repeating-Guns; and I hereby declare the following to bea full, clear, and exact description of the same.

My invention relates to certain improvements in that class of weaponsknown as magazine-guns or repeaters. It is espe cially applicable toshotguns having two barrels upon a single stock.

It consists of a stock having two barrels mounted thereon so as to slideforward and back, a mechanism whereby loaded shells are carried from themagazine and introduced into the barrels of the gun, and in certaindetails of construction in connection therewith, which will be morefully explained by reference to the accompanying drawings, in which-Figure 1 is a vertical section taken through the nearest barrel, showingthe rear portion in dotted lines. Fig. 2 is a plan view of the stockwith the barrels removed. Fig. 3 is a transverse section of the barrelsat 2 2, Fig. 1, looking to the rear. Fig. 4 is a transverse view of thepinions and disengaging mechanism. Fig. 5 is aseparate view of thesliding disengaging-plates. Fig. 6 is a section showing the pin andspring to hold the bottom of the cartridge. Fig. 7 is a perspective viewshowing one of the doors open.

Ais the stock of the gun; B, the front extension of the stock, calledthe fore-end, O, the barrels, adapted to slide backward and forward uponthis fore-end, and D is the casing within which the operating mechanismis contained.

' My present inventlon 1s an improvement on my former patent, No. 450,77 3, dated April 21, 1891; and it consists in certain improvements ofparts of the operating mechanism.

The first portion of my improvement relates to the construction of thelocking-latch F, by which the barrels are held in place when closedagainst the breech, and the mechanism by which it is unlocked to allowthe barrels to slide forward and back. This latch engages acorresponding slot K in the the spring G, and the lower part of the Webwill slide over the latch until the locking-slot arrives in line withthe latch,which will then be forced upward by the spring to engage withthe slot and lock the barrels in place.

The latch F is connected with the front end of a bell-crank lever H. Theother arm of this lever is connected with a rod I, which extends backinto the casing D and is there connected with a trigger J, which ispivoted or fulcrumed in the stock, as shown.

The catch K, which engages aslot K in the rib between the barrels andthrough which power is communicated to slide the barrels forward andback, is fixed to the outer end of a bar L, this bar being connectedwith a rack-bar N, through which motion is communicated to the pinionsP, as described in my former patent. The slot K is long enough to allowthe barrels to move forward sufficiently to expose the length of acartridge before the rear end of the slot strikes the lug K and actsthrough the rack and pinion to elevate the cartridge carrier. In thepresent case the bar L extends upwardly vertically a short distance fromits point of connection with the bar N, and thence extends horizontallybeneath the barrels to the point where the upturned catch K is formedupon it.

Beneath the front end of the bar L is a plate M, connected by a stem orshank with a button 1' which is set into a depression in the under partof the fore-end of the stock. The stock is slotted, so that the buttonand the shank may be moved backward or forward a short distance,carrying with them the plate M. lVhen these parts are pressed to wardthe rear of the gun, the plate M lies beneath the bar L, and the latterslides backward and forward above this plate and is prevented by it frombeing depressed.

When it is desired to remove the barrels, it is only necessary to pushthe button M forward, carrying with it the plate M, until it is beyondthe front end of the catch K, when the lever L and the catch may bedepressed, so that the latter is disengaged from the slot in the rib ofthe barrels and will allow the barrels to slide out at the front end.

The doors T, through which the cartridges are introduced into themagazine, are hinged at their lower edges upon each side of the magazineor chamber beneath the barrels, and when closed they are held in placeby a positively-acting latch 25, which engages with a correspondingcatch '6 upon the side of the gun.

'wis a spring, which throws the door Topen when the catch has beendisengaged.

'v is a sliding pin extending into the front end of the magazine-casing,and when it is pressed upon it releases the catch 2, so as to allowthedoor T to fly open.

w is a spring acting against the pin 1) and returning it after it hasbeen pressed inwardly, thus leaving the parts in position, so that thedoors may be shut and latched again.

In order to adjust the cartridge and hold the front end up, so that itwill be in position to enter the barrel when raised to the proper point,I have shown a catch U, which takes hold of the lower end of thecartridge-rim, provided with a small spring V, fitted in the chamber inthe rear of this catch and acting to force it forward, and this servesto slightly raise the front end of the cartridge or to counteract thetendency of the front end to settle down below the rear end, and thismaintains the front end of the cartridge in proper position to enter thebarrel.

The vertically-sliding rack-bars Q, which carry the segments S, by whichthe shells are raised to the point opposite the barrel, are in thepresent case formed with one corner of each cut out, so as to fit intothe guides in which they move and by which they are retained in place,as plainly-shown in Fig. 2. This construction is more satisfactory thanto make them of a bevel or dovetailed form in cross-section.

The pinions P are rotated by the reciprocation of the rack-bar N, andthese pinions turn loosely upon a transverse shaft 0 and have an endmovement by which either of them may be temporarily disengaged from therack-bar to prevent any action of the mechanism connected with it whilethe other is allowed to act, so that one barrel may be loaded withoutaffecting'the other.

In my present construction the vertical shaftp has a collar j fixed uponit, and the two springs r have their front ends fixed in this collar.These springs extend rearwardly and are engaged by pins Z, which holdthese ends in place. Upon the upper end of the shaft 19 is the lever g,which may be turned to either one side or the other. Projecting from thefront of the shaft p is a pin 0, which, when the lever q is turned toone side or the other, engages one of two horizontally-sliding plates m.These two plates have their ends slotted, as shown, and these slots fitover screws m, these screws serving as guides. upon which the plates maytravel.

The operation will then be as follows: The lever (1 being pressed to oneside, the shaft p will be correspondingly turned and the pin 0 will bemoved in the opposite direction, pressing against the edge of one of theplates m, as the case may be, and forcing this plate to one side. Eachplate has a lug n, extending downward and engaging a groove in thecollar n atone side of one of the pinions, and when one of the plates ismoved outward its lug, engaging this groove in the collar, forces thepinion to one side until it is disengaged from the rack-bar N. Beingheld in this position it is possible to move the loading mechanism uponone side while the other remains stationary. As soon as the lever q isreleased, the elasticity of the springs'r' will immediately return theshaft p and the other parts to the center, and the small coil-spring s,which surrounds the pinion-shaft, acting against the end of the pinionor its collar, will force it back into place again. The hammers arelocked after the gun has been cocked by means of the safety-catches c,and these catches are released by the sliding button h, fitting upon thetop of the stock and connected with the movable plate g, which engagesthe lockingcatch. The rack-bar R, which is operated by the pinions P tocook the gun,also acts upon this slide by reason of the engagement ofits rear end, so as to force the slide back when ever the gun is cooked,and this allows the locking-catch to engage the tumbler and prevent thehammers from falling. In order to release the hammers, it is onlynecessary to move the slide 9 forward again by means of the button h.

In the present case I have shown the hammer fulcrumed at to, having aprojecting lug upon the rear side of the f ulcrumed arm which is engagedby a bar ,2, extending rearwardly within the casing, having its rear endpivoted or fulcrumed at A stout coil-spring z is placed beneath thisfulcrumed bar, and, acting upward against it, power is transmittedthrough it to move the hammerwhenever the latter is released by pullingthe trigger.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is

1. Arepeating-gun consisting of a stock, one or more barrels adapted toslide forward and back in guides upon the fore-end of said stock, ahorizontally-moving rack-bar connected with the barrels, pinions andvertically-moving carriers actuated thereby, m agazines situated beneatheach of the barrels, adapted to contain loaded cartridges,springactuated hinged doors opening outwardly from the sides of eachmagazine, latches upon said doors engaging catches upon the gunframe,whereby the doors are positively locked when closed, sliding spring-pinswhereby the latches maybe disengaged to allow the doors to open, andsprings by which the pins are returned to their normal position afterbeing released, substantially as herein described.

2. A repeating-gun consisting of the stock, one or more barrels slidingin guides upon the fore-end of said stock, a pinion and rackbarsconnected with the barrel, intermediate mechanism whereby cartridges aredelivered from the magazine to the barrel of the gun by theforward andbackward movements of said barrel, a spring-actuated locking-catch, arod connected with a trigger and extending along the lower part of thestock, and a bellcrank lever, on e end of which is connected with therod and the other with the locking-catch, whereby the latter may bedepressed, substantially as herein described.

3. A repeating-gun consisting of the stock, one or more barrels slidingin guides upon the fore-end of said stock, a pinion and rackbarsconnected with the barrel and actuated by the forward and backwardmovements thereof, a mechanism whereby a cartridge is delivered from themagazine into the barrel of the gun, a groove or channel extendinglongitudinally beneath the barrel of the gun, a catch projecting intosaid groove, so as to be engaged and moved by the opposite ends of thegroove when the barrels are moved forward or backward, a rod extendingfrom said catch and connected with the horizontallymoving rack-bar, aplate M upon which the front end of said bar is supported in itsmovements, and a button M, connected with the plate, whereby the lattermay be moved so as to support the bar or to release it and allow it andthe catch to be depressed and disengaged from the barrels, substantiallyas herein described.

4:. The T-shaped hammer having the long arm fulcrumed in the lower partof the casing in which it is contained and a lug projecting rearwardlybehind the fulcrum-point, in combination with the bar z',fulerumed atthe point 52, and the spring ,2, acting upon said bar and through itupon the hammer, substantially as herein described.

5. A repeating-gun consisting of a pair of barrels moving in guides uponthe fore-end of the stock, a rack-bar connected bya link with saidbarrels, two pinions journaled upon a horizontal shaft and normallyengaged and rotated by the movements of said rack-bar, independentvertically-movin g rack-bars and carriers for each barrel, each actuatedby one of said pinions, springs by which said pinions are normallypressed toward each other, so that both are engaged and actuatedsimultaneously by the main rack-bar, a lever upon the top of the gun, avertical shaft to which said lever is fixed, a pin projecting from saidshaft to engage transversely-sliding plates, one movablein eachdirection by the opposite movement of said lever, lugs projecting fromsaid plates, and grooved collars connected with the pinions, one ofwhich is engaged by each of said lugs, .whereby the movement of thelever in either direction willv disengage one of the pinions and theloading mechanism from the main rack-bar, substantially as hereindescribed.
